I am using VLC do play back audio from my HiFiBerry Digi+ board.
1.) What is the difference between
"Direct hardware device without any conversions"
"Hardware device with all software conversions"
I can also see these options when I do an "aplay -L" command a the linux prompt.
When would a person want to use one or the other?
You can see the last two items from the screen shot below.
2.) I used to be able to use the alsamixer command and adjust the volume with the software plugging to adjust the master volume.
I am not sure what I did, but now if I select "Hardware device with all software conversions" I don't hear any audio and the volume adjustments in alsamixer do nothing.
If I switch over to "Direct hardware device without any conversions" I hear the audio but not able to adjust the volume with alsamixer.
Any ideas on this?
